View the Exhibit and examine the structure of the ORD table. Evaluate the following SQL
statements that are executed in a user session in the specified order: CREATE SEQUENCE
ord_seq; SELECT ord_seq.nextval FROM dual; INSERT INTO ord VALUES
(ord_seq.CURRVAL, 25-jan-2007′,101); UPDATE ord SET ord_no= ord_seq.NEXTVAL
WHERE cust_id =101; What would be the outcome of the above statements?
A.
All the statements would execute successfully and the ORD_NO column would have the
value 20 for the CUST_ID 101 because the default CACHE value is 20.
B.
All the statements would execute successfully and the ORD_NO column would contain
the value 2 for the CUSTJD 101.
C.
The CREATE SEQUENCE command would not execute because the minimum value
and maximum value for the sequence have not been specified.
D.
The CREATE SEQUENCE command would not execute because the starting value of
the sequence and the increment value have not been specified.
